Abstract

When highly polymerized deoxyribonucleic acid is digested with pancreatic DNase and the digest further degraded with phosphodiesterase from intestinal mucose or snake venom, the mononucleotides formed are 5'-phosphates. Since a digest prepared in this manner with a purified venom diesterase contains only 5'-mononucleotides and practically no nucleosides or polynucleotides, the pancreatic DNase must form only polynucleotides with 5' monoesterified phosphate end groups. Recently the enzymatic synthesis of polydeoxyribonucleotides from eoxyribonucleoside 5'-triphosphates has been demonstrated. Thus both enzymatic synthesis and degradation of deoxyribonucleic acids have as yet involved only derivatives with 5'-monoesterified phosphate.
